An interval adjusting apparatus for an arching horn is provided to adjust a gap of the arching horn more accurately by allowing a gap between a ground side arching horn and a cable side arching horn to be adjusted minutely by a revolution of a handle. In an interval adjusting apparatus for an arching horn, a movable bracket(30) includes a ground side arching horn at an upper part and a slide pipe joint(32) which has a pin hole(34) formed in a perpendicular direction to an axis and is welded horizontally on a right side thereof. A fixed bracket(40) includes convex-shape vertical ribs(44,46) on an inner wall of a block coupling groove(42) formed as an U-shape. A guide pipe fixing block(50) includes concave-shape grooves(51,52), slidingly coupled with the vertical ribs(44,46) on a front and rear vertical sides, a guide pipe fixing bar(53) at a left side, and a rotary axis insertion hole(54) and an air ventilation hole(55) in a center. A block cover(56) surrounds the guide pipe fixing block(50) by being coupled with the upper part of the fixed bracket(40) with crossing forward and backward and includes a cable side arching horn(26) facing the ground side arching horn(22) formed on an upper side vertically. A hexagonal guide pipe(60) is fixed to the guide pipe fixing bar(53) by a screw coupled. A hexagonal slide pipe(64) inserted into the hexagonal guide pipe(60) includes a scale(66) on an outer face in a length direction. A nut(67) welded on a right end of the hexagonal slide pipe(64) includes a rotary axis guide hole(68) in a center, penetrated in a left/right direction, and an air flowing hole(69) around the rotary axis guide hole(68). A rotary axis(70) inserted into the rotary axis guide hole(68) and rotary axis insertion hole(54) includes stopping grooves(73,74) receiving snap rings(71,72) closely adhered to left and right sides of the guide pipe fixing block(50) and an external screw unit on a left end. A handle is fixed to a right end of the rotary axis(70). A slip joint placed between the hexagonal slide pipe(64) and the slide pipe joint(32) absorbs a rotation moment applied in a direction, opposite to the hexagonal slide pipe(64) and the movable bracket(30).
